Good quality product.
Chunky heavy brass.
Amazing product have had 3 bottles over last few years, very pleased with the outcome of this product,
Only one i could find on the Internet, fitted perfectly.
It has been used in the water pump of my 1923 Aston Martin. However, I had to 'unwind it' into cord strips. I have found that keeping in it original form keeps it from drying out, ready for next time.
